Are Casper Mattresses Firm? Understanding Their Feel and Support

If you’re wondering “Are Casper Mattresses Firm?”, you’re likely trying to figure out whether their feel will match your comfort needs and sleeping style. Firmness can be confusing because it’s subjective—what feels firm to one person may feel medium or even soft to another. This guide breaks down how firmness works, what people usually mean when they ask about Casper, and how to decide if their typical feel is right for you.

What Does “Firm” Really Mean for a Mattress?

Before answering “Are Casper Mattresses Firm?”, it helps to clarify what “firm” usually refers to:

  • Firmness describes how hard or soft a mattress feels when you lie on it.
  • It’s not the same as support. A mattress can feel soft on top but still keep your spine aligned.
  • Many mattress brands design around a medium to medium-firm feel because it tends to work for a wide range of sleepers.

When people ask if a certain mattress is firm, they often want to know:

  • Will I feel like I’m sinking in too much?
  • Will it keep my back supported?
  • Will it feel comfortable in my usual sleep position?

So, Are Casper Mattresses Firm Overall?

In general, many sleepers experience Casper-style mattresses as medium to medium-firm, rather than extremely firm.

Most models from this type of brand aim for a balanced feel:

  • A slightly plush or cushioning top layer
  • Underneath, foam or hybrid layers that feel supportive and stable
  • Often described as “not too soft, not too hard”

For someone used to a very hard innerspring bed, this might feel less firm. For someone used to a very soft, deeply contouring foam bed, it might feel firmer and more supportive.

Key idea: When people ask, “Are Casper Mattresses Firm?”, the practical answer is that they typically sit around a medium-firm zone, designed to suit a wide variety of sleepers rather than being extra-firm.

How Does Firmness Feel for Different Sleep Positions?

Back sleepers

Many back sleepers often prefer a medium-firm surface:

  • Enough give to allow the hips to settle slightly
  • Enough support to prevent sagging in the lower back

For these sleepers, Casper-style mattresses often feel supportive without being rock-hard.

Side sleepers

Side sleepers usually need more pressure relief at the shoulders and hips.
On them, a medium-firm mattress can feel:

  • Comfortable for some, especially if there’s cushioning on top
  • Slightly firm for lighter side sleepers who don’t sink in as much

Stomach sleepers

Stomach sleepers often look for something that doesn’t let the hips dip too far:

  • A medium-firm feel can work well for many
  • Those who strongly prefer an extra-firm surface might find it moderately firm but not ultra-firm

Why Do Some People Say Casper Mattresses Feel Firm?

If you still find yourself asking “Are Casper Mattresses Firm?”, it may be because different people describe the same mattress differently. A few reasons:

1. Body weight and shape

  • Lighter sleepers may experience the mattress as firmer, since they don’t sink as deeply into the comfort layers.
  • Heavier sleepers may feel more of the underlying support layers and might describe the bed as medium rather than truly firm.

2. Previous mattress type

  • Coming from a very soft pillow-top: a medium-firm foam or hybrid surface can feel noticeably firmer.
  • Coming from a hard, thin mattress: the same bed might feel more cushioned and less firm.

3. Sensitivity to pressure

Some people are more sensitive to pressure at the shoulders, hips, or lower back. For them, even a balanced medium-firm mattress can initially feel “too firm,” especially when new.

How to Tell If Their Typical Firmness Is Right for You

When trying to decide if the usual feel will suit you, focus on a few practical questions instead of just labels like “firm” or “soft”:

Ask yourself:

  • What do I sleep on now? Does it feel too soft, too firm, or about right?
  • Do I wake up with pressure points at the shoulders or hips?
  • Do I feel my lower back is supported, or do I sink too deep in the middle?
  • What’s my main sleep position? Side, back, stomach, or a mix?

💡 Simple guideline:

  • If you like balanced support with some cushioning, the typical Casper-style feel (often near medium-firm) may be close to what you’re looking for.
  • If you only feel comfortable on very hard beds, you may find it less firm than you prefer.
  • If you sink deeply into soft mattresses and want something more stable, it may feel noticeably firmer and more supportive.
